Telegram Splitting for Slotted Aloha

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent presents a method and system for transmitting small data packets more efficiently in mobile communication systems, such as those following 3GPP standards. It achieves this by splitting a message (telegram) into several smaller data packets, each sent separately in different resource elements (e.g., different times or frequencies available in the communications grid). This 'telegram splitting' for Slotted ALOHA access allows systems serving many devices, like those in machine-to-machine (M2M) communication, to reduce power consumption and increase the effective use of the available communication bandwidth.

Use CasesContent extracted from patent full text and abstract with AI.

• Internet of Things (IoT) sensor networks, where many devices need to transmit small amounts of data efficiently and reliably.
• Smart city infrastructure communications, such as smart meters and environmental sensors.
• Vehicle-to-vehicle (V2V) or car-to-car (C2C) communication for sending quick alert or status messages between cars.
• Industrial automation systems with a large number of devices needing low-latency, low-power data transfer.
• Remote monitoring applications, such as in agriculture or infrastructure health monitoring, where devices have limited power supplies.
• Emergency alert or notification systems that require quick and reliable broadcast of small packets to many recipients.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces power consumption of devices by minimizing communication overhead, important for battery-operated devices.
• Improves spectral efficiency by making better use of available communication resources, which is critical with high device density in M2M or IoT systems.
• Reduces communication latency as devices can transmit small data packets without a lengthy allocation or negotiation process.
• Provides robustness against packet collisions through error correction and the use of Slotted ALOHA, increasing the reliability of data transmission in noisy or crowded wireless environments.
• Enables dynamic allocation of communication resources based on real-time needs and network performance, increasing overall flexibility.
• Compatible with existing communication standards (e.g., 3GPP, LTE), allowing easier integration into current networks and devices.

Patent Abstract

Embodiments provide a transmitter, configured to operate in a mobile communication system according to a mobile communication standard (e.g., 3GPP), wherein resources of the communication system are divided into resources elements. The transmitter is configured to transmit an additional telegram by separating the telegram into a plurality of data packets, each of the data packets being shorter than the telegram, and transmitting each of the data packets respectively in one of the resource elements.
